I seemd to have the BIOS setup correctly, although at the moment I have had to unplug my CD-ROM and 250gb HDD whilst trying to get it working.

I attempted to install XP on the newly formatted 80gb HDD and it got through to the stage of copying files, the windows logo came up, then it told me to reboot. On reboot it got the windows logo, then the dreade blue screen flashed up with the following message :

"A problem has been detected and windows has been shut down to prevent damage to your computer.

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again (it did, 3 times), follows these steps :

another thing you can try is to put in your windows CD, then restart the PC. It should display a small message to press any key to load from CD. Do that and load windows. You should have an option to fix your windows install at this point.

I have randomly seen that message myself, but what causes it i have no idea.
